17:46
Disable the undocumented rtreenode() SQL function that is only used for testing, except when doing a build that is specifically intended for testing. (check-in: 0a1cce49 user: drh tags: branch-3.18)
2018-12-19
17:05
Add new interfaces sqlite3_result_pointer(), and sqlite3_value_pointer() and use them to transfer the eponymous FTS3 column pointer to the snippet() and offsets() routines. Cherrypick from commit [8201f4e1] on branch-3.18. (check-in: 553a923c user: dan tags: branch-3.19)
14:44
Fix a crash that can follow an OOM in fts3 on this branch. (check-in: de078148 user: dan tags: branch-3.19)
01:44

01:38
Add extra defenses against strategically corrupt databases to fts3/4. (check-in: 4bb21d82 user: drh tags: branch-3.18)
2018-03-16
07:49
Fix a problem in test script thread001.test causing a spurious "-1 files were left open" error when run separately. Cherrypick of [1774f1c3b]. (check-in: 6cf8172d user: dan tags: branch-3.19)
2018-03-06
11:49
Avoid running a couple of tests in crash8.test that depend on the presence of the journal file if running on an F2FS file-system that does not require a journal file. Cherrypick of [797e02e0]. (check-in: eeedfc74 user: dan tags: branch-3.19)
2018-02-02
08:14
In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. (check-in: 22a228ed user: dan tags: branch-3.19)
08:08

14:50
Add the new sqlite3PagerUnrefPageOne() pager method to deal with the special case of unreferencing page1. (check-in: b2e2100c user: drh tags: trunk)
